J. H. WALBRIDGE BALLAST REMOVING MACHINE Filed Sept. 15, 1932 2 Sheets-Sheet l INVENTOR ATTORNEYS When it is desired to move the scraper to inoperative position, for example, when the machine is advanced through turn-outs or permanent highway crossings, the scraper members are disconnected as described above and swung into inverted position on top of the guide membe s as described above.

From the above description, it will be apparent to those skilled. in the art that I-provide an improved ballast removing machine which is highly effective in operationthe machine being provided with means for maintaining the true grade of the road bed. While I have not gone into detail concerning the means for controlling the operation of the various power units,'it will be understood that conventional controls are used. l j in order to facilitate the adjustment of the apparatus to a predetermined grade, pointer fingers 34 are provided which project laterally from some fixed part of the frame into position-to cooperate with a grade stake or the like.

I have illustrated and described my improve ments in an embodiment which I consider very practical. I haven-0t attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable those skilled in the art to embody or adapt my imadvancing said carriages.

provements as may be desired.

Having thus described invention, what I claim as new and Wish to secure by Letters Patent is:
